WINDOW-SCREEN.

To all whom it may concern:

Be it known that l, CARL E. Bownn, a citizen of the United States,residing at Bethel, in the county of Shelby and State of Missouri, haveinvented new and useful Improvements in Window-Screens, of which thefollowing is a specification.

The invention relates to window screens and has for an object to providea screen that can be varied in length and width in order to adapt thescreen for use in connection with windows of various sizes anddimensions.

The invention embodies, among other features, a frame adapted to carrythe usual screen wire and which consists of sides and ends which arerelatively adjustable and connectible, and brace members for use inconnection with the said sides and ends to secure the same in relativelyrigid position.

In the further disclosure of the invention reference is to be had to theaccompanying drawings, constituting a part of this specification, inwhich similar characters of reference denote corresponding parts in allthe views, and in which:

Figure 1 is a side elevation, showing the side and end members inposition prior to assembling the same; Fig. 2 is a vertical 1ongitudinalsectional view taken through the screen frame, showing the sides andends in initial position; Fig. 3 is a similar view showing the sides andends in final and secured position and the brace members arranged intightened and secured position; Fig. 4 is a side elevation of thecompleted screen, the dotted lines indicating the parts that have beenremoved from the sides and ends, the other dotted lines indicating thefinal positions of the brace members; Fig. 5 is a fragmentaryperspective view of one of the sides; Fig. 6 is a fragmentary perspective view of one of the ends; and Fig. 7 is a perspective view of one ofthe brace members.

Referring more particularly to the views, I disclose a screen 10comprising side mem: bers 11, 12, the side member 11 having a channel 11provided in one end thereof and a tenon 11 formed at the other endthereof. Similarly, the side member 12 is provided at one end with achannel 12 and at the other end with a tenon 12 the channel 12 however,being formed in the side member 12 on that end of the side memberopposite to the end of the side member 11 having the tenon Specificationof Letters Patent.

11 so that the channel 11 of the side member 11 will be opposite to thetenon 12 of the side member 12 and the channel 12 of the side member 12will be opposite to the tenon 11 of the side member 11. The end member13 is provided at one end thereof with a channel 13 and at the other endthereof with a tenon 13 and, similarly, the end member 14 is provided atone end thereof with a channel 14 and at the other end thereof with atenon 14 the channel 13 in the end member 13, however, being opposite tothe tenon 14 of the end member 14 and the channel 14- of the end member14 being opposite to the tenon 13 of the end member 13. It will now beseen that when the side members 11 12 and end members 13, 14 arearranged in the position shown in Fig. 1, the tenon 11 of the sidemember 11 will be adjacent the channel 14 of the end member 14, thetenon 12 of the side member 12 will be adjacent to the channel 13 of theend member 13, the tenon 13 of the end member 13 will be adjacent thechannel 11 of the side member 11 and the tenon 14" of the end member 14will be adjacent to the channel 12 of the side member 12, it beingunderstood that the tenons 11 12", 13 and 14 are, therefore, adapted tofit into the respective channels 14*, 13 11 and 12 of the respective endmembers 14, 13 and side mem bers 11, 12. The channels 11, 12, 13 and 14are similarly formed in the respective members 11, 12, 13 and 14, andthe channels are open at the ends of the said members and along theinner edges thereof. Now when the side members 11, 12 and end members13, 14 are connected as shown in Fig. 2, with. the tenons of therespective side members fitting into the channels adjacent which thetenons lie as shown in Fig. 1, it will be seen that a portion 14 of thechannel of the end member 14 will project beyond the side members 11,and, similarly, a portion 13 of the channel of the end member 13 willproject beyond the side member 12, while a portion 11 of the channel ofthe side member 11 will project beyond the end member 13 and a portion12 of the channel of the side member 12 will project beyond the endmember 14.

\Nl1811 the side and end members 11, 12 and 13, 14 have been arranged asmentioned, this being the desired size of the finished screen, theprojecting portions 11, 12, 13 and 14 of the respective members 11, 12,13 and 14 are cut or sawed off from the said members so that the channelends of the side members 11 and 12 will lie fiush with the outer edgesof the end members 13, 14 and, similarly, the ends of the end members13, 14 will lie flush with the outer edges of the side members 12 and 11respectively. Brace members 11 12 13 and 14 are now employed for use inconnection with the heretofore mentioned channels 11 12, 13 and 14 andwhen the side and end members 11, 12, 13 and 14 have been arranged inadjusted and connected position as shown in Fig. 2 and as describedheretofore, portions are cut off of the brace members 11 12 13 and 14,the said portions being equal to the portions 11 12 13 and 14 cut off ofthe channel ends of the respective members 11, 12, 13 and 14, and itwill thus be seen that when this has been accomplished the brace members11 12 13 and 14 will snugly fit in the channels 11, 12*, 13 and 14 withthe brace members interposed in the channels between the members inwhich the channels are formed and the tenons of the adjacent members andwhich repose in the channels, it being further seen that each of thebrace members 11 12 13 and 14 has one end beveled and the inner ends ofthe channels are likewise beveled in order that the brace members can besnugly placed in the channels and properly secured therein. Nails orscrews 15 are now arranged to pass transversely through the channel endsof the side members and end members and through the respective tenonsreposing in the channels of the side members and end members, thussecuring the ends of adjacent side members and end members, after whichnails or screws 16 are passed through the channel ends of the sidemembers and end members and through the brace members in the channels torigidly secure the brace members therein, thus completing the screen 10,it being understood that the usual screen wire employed on the screencan be tacked or otherwise secured thereon after the frame has beenadjusted to the proper size in the manner mentioned heretofore. Now inorder to permit of great accuracy in assembling the side and endmembers, the side and end members, after being arranged in connectedposition to provide a frame of the desired size, can be first nailedtogether, after which the projecting portions 11, 12, 13 and 14 are cutor sawed off, and then it will be only necessary to place the bracemembers 11 12 13 and 14 in the respective channels 11, 12 13 and 14 andsecure the same therein to complete the screen.

From the foregoing description it will be seen, therefore, that Iprovide a screen which can be varied in both length and width in orderto provide a finished screen adapted for the particular window or sashfor which it is intended, this result being accomplished without a greatwaste of material and without the use of skilled labor and high gradetools. It will also be seen that when a screen is completed in themanner mentioned heretofore the same screen can again be made smaller inboth length and width by simply removing the brace members, adjustingthe side members and end members to the desired position and againsawing off the projecting portions, the portions of the brace membersbeing then also sawed off therefrom, after which the brace members arereturned to position within the channels and secured to the respectivemembers thereof.

Having thus described my invention, I claim:

1. A screen frame comprising four similar members, each provided with alongitudinal channel opening at one of the ends of each member, a tenonformed integrally with each member and at one of the ends thereof andfitting into the channel of an adjacent member, whereby the distancebetween parallel frame members can be varied, and brace members forinsertion in the said channels between the tenons and in clined walls ofthe channels for securing the members in relatively rigid position.

2. A screen frame comprising pairs of similar side members and endmembers, with each of the said members having a longitudinally extendingchannel formed in one of the ends thereof, with one of the walls of eachchannel inclined and the channels opening through an end of each of themembers, tenons formed with the said side members and end members, withthe tenons in the end members adapted to extend into the channels of theside members and the tenons of the side members adapted to extend intothe channels of the end members, whereby the members in each pair may bearranged in relatively spaced relation so that the distance between themembers in each pair can be varied, and brace members having inclinededges and adapted for insertion in the said channels and interposedbetween the said tenons and the solid portions of the said members.

In testimony whereof I afiix my signature in presence of two witnesses.
